SPECIFICATION forming part of Letters Patent No. 487,397, dated December 6,1892.

Application tiled April '7, 1892. Serial No. 428,216. (No model.)

To all whom it may concern:

Be it known that we, JULIUS F. STONE, residing at Oolumbus, Franklin county, and FRED M1LLER, residing at Corning, Perry county, State of Ohio, citizens of the United States, have invented certain new and useful Improvements in Pumps; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The water and other tluids in mines is frequently mixed with powerful corrosives that soon destroyor render useless pum ps of metal used in expelling it. As wood successfully resists the action of these deleterious substances, we have devised a pump especially adapted for use in mines, which are usually constructed almost wholly of that material. The novelty in our case resides in the construction of valve-chamber for such pumps, substantially as hereinafter described and claimed.

In the accompanying drawings, Figure 1 illustrates a sectional view of the valve-chambers and pipes or water-ways connecting them. Fig. 2 illustrates a similar viewof a pumpingengine, the pump-pistons, and suction-chambers. Fig. 3 illustrates a top plan view of one end of our pump, the parts being in operative position.

Like characters of reference in the different figures indicate corresponding parts.

The letter Adesignates the valve-chamber, which is constructed of three sections 1, 2, and 3, of wood. The lower section 1 is bored centrally to receive the short piece ct of the induction-pipe. In boring this section a bridge 4: is left extending diametrically across the opening and in the direction of the grain of the wood to receive a pairof valves 5 5. The middle section 2 is made with a tapering passage or chamber and with a bridge like that in section 1, also to receive valves, as shown. The bore or opening of section 2 is made larger at its lower end, so as to allow room for the play of the valves 5 and afford a place on the surface of section 1 around the bore thereof for the reception of a metallic valve-seat 10. The lower surface of section 2 is rabbeted,as shown, and rests upon the metallic valve-seat and holds it in place. A port 9, the position of which is shown by projection only in Fig. l, is also made in the side of section 2. Section 3 of the valve-chamber is made with a cylind ricl bore somewhat larger than the opening at the upper end of the bore of section 2, so that when section 3 is in position a place remains for an annnlarvalve-seat 11, of metal or wood or composition. This valve-seat is held in position bythe lower end ot' a tube E, of wood, which fits removably in the bore vof section 3. The upper end of the chamber formed by the bore in section 3 is closed bya cover or lid held firmly in place by nuts on the ends of bolts 12, which pass vertically through section 3. The sections l, 2, and 3, which compose the valve-chamber, are held securely together by bolts passing vertically through them. The sections are further strengthened by similar bolts passing horizontally through them. Washerstrips 13, of metal, may be placed under the nuts on the ends of the bolts.

In the drawings we have shown two valvechambers alike in construction, one being a complement of the other, and they are supplied byacommon induction-pipe 1l, of wood. Theupper or eduction compartments of the valve-chambers are connected by means of a Wooden pipe 15 and a common outlet-pipe, as shown at 16. The pipe 15 has its ends rabbeted, as shown at 17, so as to afford a shoulder against which section 3 may abut and be tightly drawn by bolts 18, which extend from one chamber to the other.

The pumping-engine D is of usual construction. The plungers 6 G work in suctionchambers C C,made from cube-like blocks of wood bored centrally. Plates 7 7,which close the outer ends of the suction-chambers, and

plates or heads 8 S, through which the plungers 6 6 pass, are secured in their .respective places by means of bolts passing horizontally through the block constituting the suctionchamber. The pumping apparatus is given additional stability by bolts 19, (see Fig. 3,) passing through tubes 20 interposed between the plates 7 7 and heads 22 22 of the steamcylinder.

The pumping-engine B and the suctionchambers O are secured by means of bolts or other suitable tastenings upon a bed D.

Ports 21 are made through the sides of the suction-chambers C C, and the position and form of these ports are such that when the valve-chambers A are placed against the suction-chambers C, as shown in Fig. 3, they will be united and the pump ready for operation.

The Working of the pump will be readily understood by those acquainted with the subject. The pipe 14 is connected with the water to be removed from the mineand upon the operation of the engine the Water is drawn (so to speak) into either Valve-chamber and simultaneously forced outof the otherinto the eduction-compartments thereof and through the common outlet-pipe 16 to the surface of the earth.

It Will be obvious to those familiar with mining operations that the valve-chamber herein shown and described is of simple, cheap, and durable construction, that it will successfully withstand the destructive action of mine-Water, and that the parts most subjected to Wear may be readily taken apart and easily put together for repairs.

Having thus described our invention, what We claim, and desire to secure by Letters Patent, is-

In a pump of the kind described, a valvechamber composed of superposed bored Wooden sections 1 2 3, the section 3 having the removable tube E in its bore, a metallic valveseat 10, resting upon the section 1 and held in position by the section 2, and a metallic valve-seat resting upon the section 2 and held in position by the removable tube E in the bore ot' the section 3, substantially as shown.

In testimony whereof we afx our signatures in presence of tWo Witnesses. Y
